Paint Thinners and Solvents

paint thinners and solventspaint thinners and solvents

Paint thinner and solvents must be handled with care because they are petroleum-based products, which are toxic and flammable. If the contents are swallowed or fumes inhaled, serious injury can follow. Fumes accumulate invisibly in closed spaces (like small rooms and sheds) and can reach dangerous levels. Improper use or disposal can also pollute our soil and water.

Reduction Tips

To reduce the need for solvents and thinners, choose water-based alternatives when buying paint, stain or varnish. These products only require soap and water for clean-up. To protect your air quality, choose products that produce less toxic fumes. Ask retailers to show you their line of products featuring lower levels of volatile organic chemicals - low VOCs.

For more information on reducing toxins in your home, consult the resources of Reduce.org, a service of the Minnesota Pollution Control Agency.

Disposal Information

Solvents and thinners should never be placed in the garbage, poured down the drain or on the ground. Take them to a county household hazardous waste collection site for disposal.

Follow these tips for safe use, storage and transport:

  • Follow the label instructions for safe use and proper storage instructions.
  • Avoid breathing fumes. Carefully ventilate work areas, storage spaces and vehicles when transporting solvents.
  • Do not mix solvents.
  • Do not fill containers full; solvents need room to expand.
  • Never smoke around solvents or in a room where solvents have been used recently.
  • Store solvents in a labeled container out of reach of children and pets, preferably in a locked cabinet.
  • Store solvents away from flames, sparks and heat sources.
  • Store and transport solvents in sealed containers.
  • Transport solvents in the trunk of a vehicle if possible, but don't store solvents in the trunk.
